(Cl. 1Z0-50) 7 Claims.

This invention relates to a fountain pen, more particularly to thesecuring of the pen holding member in the barrel thereof.

In the usual fountain pen the pen holding member is provided withthreadsv integral therewith which receive the cap of the fountain pen.The material is usually non-metallic and difficulty sometimes occurs inthis threaded joint.

One of the objects of this invention is to provide means for holding thepen holding member -in position and at the same time improving thethreaded joint between the cap and pen holding member.

Another object of this invention is to provide a metal band with themetal parts thereof functioning to provide one part of the threadedsurface which exists between the pen holding member and the cap and thepen holding member and the barrel.

Another object of this invention is to provide a thimble which may bereadily positioned and which will contain the threads of parts to beengaged for greater strength construction.

With these and other objects in View, the invention consists of certainnovel features of construction, as will be more fully described andparticularly pointed out in the appended claims.

In the accompanying drawings:

Fig. l is an elevation of a fountain pen;

Fig. 2 is a sectional view showing fragmentally the upper portion of thepen and illustrating on an enlarged scale the invention;

Fig. 3 is a sectional view of the pen holding member;

Fig. 4 is a sectional view of the thimble which engages the pen holdingmember for positioning the same.

In proceeding with this invention, I provide a pen holding member whichis so shouldered that there will be an abutment surface to engage theupper end of the barrel and an abutment surface to be engaged by athimble which extends thereover to draw the pen holding member intoposition in the barrel and securely retains it there. The thimble isformed of metal to provide a better wearing surface for the threads anda strengthening of the barrel end.

With reference to the drawing, I designates the barrel of a fountainpen, Il the cap thereof which has retaining clip I2 thereon. The barrelI0 has an open upper end, the end portion of the walls of which isreduced as at I4 and provided with a thread I5, The pen holding memberI6, shown by itself in Fig. 3, is provided with section I'I intermediateits ends with a reduced upper end portion I8 forming a shoulder I9 andreduced lower portion 20 forming a shoulder 2|. Portion 20 is of a sizeto nt the interior 22 of the barrel and is further reduced as at 23 forreception of the collapsible section 24 as shown in Fig. 2. An inkcontrolling member 25 is mounted in the upper end of the central bore 26of this member and this member also assists in retaining a pen 21.

The member I6 is fitted into the upper end of the barrel, as shown inFig. 2, so that its shoulder 2| engages the end 28 of the barrel. Aferrule 30 of metal has a lip 3| to engage the shoulder I9 and isscrewed onto threads I5 so as to draw the member I6 into the barrel andhold it securely in position. The lower portion of the ferrule 33 is atits outer surface substantially flush with the outer surface 34 of thebarrel so as to continue the diameter thereof and provide a band ofmetal. In order to retain the cap I I in position this ferrule isreduced in diameter as at 35 and provided with threads 36 for receivingthe threads 31 on the lower end of the cap II which may be screwed ontothese threads and against the shoulder 38 formed by this change indiameter. This ferrule strengthens the entire assembly and protects itin case of abuse.

The threads 32 and threads 36 on this ferrule, which may be made ofmetal or some more wearresisting material than the plastic or rubber ofthe remainder of the pen, may be right-hand threads 36 and left-handthreads 32 so there will be no danger of removing the ferrule when thecap is removed. Further the threads 32 may be a closer fit and thus oneof considerably more friction so that there will be no danger ofremoving the ferrule from position when removing the cap on the pen.

I claim:

1. A fountain pen comprising a barrel member having an open top and athreaded external surface, a pen holding member having an externalshoulder and a ferrule having a lip to engage said shoulder `andinternally threaded at one end to engage said external threads and holdsaid members assembled.

2. A fountain pen as set forth in claim 1 wherein said pen holdingmember is provided with a section larger than the interior of saidbarrel terminating in surfaces at right angles to its length to provideshoulders with said ferrule en gaging one shoulder and drawing the othershoulder against the open top of said barrel.

3. A fountain pen as set forth in claim 1 Wherein the threaded top ofsaid barrel is reduced in 3 size from the diameter next adjacent in Ianamount such that said ferrule will be flush with the said next adjacentdiameter of the barrel when in position thereon.

4. A fountain pen as set forth in claim 1 Wherein threads are presentedon the outer surface of said ferrule'to receive a cap.

5. A fountain pen as set forth in claim 1 Where; in said ferrule isrigid metal.

6. A fountain pen as set forth in claim 1 where-y in threads arepresented on the outer surface of said ferrule to receive a cap and saidthreaded portion is of a reduced diameter from the adjacent diameter.

7. A fountain pen as set forth in claim 1 where- 15 4 in threads arepresented on the outer surface of said ferrule to receive a cap and saidthreaded portion is of a reduced diameter from the adjacent diameter inan lamount substantially the 5 thickness of the cap to be receivedthereon.
